As mentioned on anotyher post my bike was parked up for two years, tank emptied and battery removed.
I got back on it recently filled it up and put a new battery in and it has been running swee, until a few days ago i am having some starting problems. all the lights come on and good to go but no response from the starting motor.
I thought it may be the clutch switch as I have a crappy aftermarket lever, (soon to be replaced with OEM) I have to sometimes hhold the clutch switch tight into the perch socket to engage it, but I asm used to this and I dont think that is the problem in this case.
However when I have the ignition on then hold the front brake on and rock the bike back and forth vigorously a couple of times then pull the cluctch lever and push the start button it fires up and runs ok,
My guess is a bad earth somewhere, I have breifly checked the starter and solenoid connections, they all feel tight and secure, and I cant see anything shorting out on the frame anywhere, although I havent yet pulled ithe vbile apart to trace the problem yet, I was jusrt wondering if there was any advise or pointers before I start?

yes dude, you just fixed my bike!!:love: I just tried to start it but no response then I pressed the horn whilst the starter button was still pushed it and it fired up straight away, just done it 3 times in a row. what is the problem there then? I dont mind waking the neighbours upo with a blast on the horn to start it anyway lol

The bike starts up lovely now, all it took was a single push of the horn to clear the problem, are the horn and starter buttons connected?? or was the ecu detecting a short and preventing the starter from running? How did you discover the fix?

Horn button shares the clutch switch ground lead. There is a crimp in the wiring alongside the left handlebar that corrodes. When it goes, you will lose both the horn and starting.

I don't know why pushing the horn button made a circuit, but it's temporary. Look for my old post on the repair.

NOTE TO 955 Sprint Owners - they all do it! "When" is the variable.

That wiring Gremlin happened to me. I noticed that the bike wouldn't start but when I moved my handlebars it would start. I read the post about the corrosion in the wiring. When I got the bike home I slit open the wiring harness on the left handlebar and found the Y connection had broken. I soldered it together and it's never happened again

There are corrosion issues and bad, broken or weak ground issues with my '08. I've started going through every connector and cleaning and using dielectric grease on most of them. I don't know the exact past history but with over 57k miles it's been ridden a decent amount but looks like it's lived in the southwest USA most of it's life so corrosion usually isn't that much of an issue. I also opened up some of the covered wires and fixed a couple of frayed wires.

I need to do this too, although pushing the horn seemed to clear the problem but it came back, I put an OEM clutch handle back on the bike and It fires up on the spot straight away, I also had a look around some of the suspect areas mentioned earlier in this thread and I can see some rusty corroded looking bits, when I got the bike there was some small led lights threaded through the frame and bodywork, which looked crap so I removed them or so I thought, as I found a couple of thin wires which used to have these little lights on the end but have rotted away, I scrunched the wires away from the frame with a view to attend to them later, this along with the new clutch handle has transformed the start up experience altogether...bliss, I must go through the wiring though while I have the mind to.
